Abstract

In one embodiment, a local oscillator and mixer architecture may include a frequency divider having I and Q channel master storage elements formed of devices of a first size, and I and Q channel slave storage elements formed of devices of a second size, where the second size is smaller than the first size. In such manner, power consumption may be reduced while reducing phase noise in signals provided from the frequency divider to the corresponding mixer.
